Ave Core EUVD-2026-15742

Risk assessment is constrained by the absence of CVSS vector data, EPSS scores, and KEV confirmation status. However, the nature of the vulnerability class (CWE-862: Missing Authorization) combined with the Patchstack report and ENISA EUVD designation (EUVD-2026-15742) indicates a genuine access control weakness. The attack vector is likely Network (given it is a WordPress plugin), and complexity is probably Low (broken access control flaws typically require no special conditions). Given that this affects a core plugin framework, the technical impact is potentially High—attackers could escalate privileges, modify content, or access sensitive data. Without POC or exploitation telemetry, this should be prioritized based on deployment breadth: any organization running Ave Core ≤2.9.1 faces real exposure and should treat patching as urgent, particularly if the plugin manages administrative functions.

An attacker discovers that the Ave Core plugin fails to verify user capabilities before processing sensitive administrative requests (e.g., content modification, user creation, or settings changes). By crafting a direct request to a vulnerable endpoint without proper capability checks, the attacker—potentially without authentication or with a low-privilege user account—can trigger protected operations. The Network attack vector and likely Low complexity mean exploitation requires only network access and HTTP requests, making this exploitable at scale against unpatched WordPress installations using Ave Core.
